Truce looks between Crowley and Valkyrie dubiously. It seems presumptuous to him that Crowley would just bring in anyone he wished into their Cabal without first speaking with him about the decision. He remembers seeing her briefly at the memorial service. At least she had met Einstein before now.
Despite his misgivings he smiles softly. Valkyrie appears pleasant for the most part so he doesn't wish to bring up what could be an embarrassing discussion. Likely they would all be discussing the matter of the new addition soon enough.
"A pleasure to meet you, Valkyrie. I look forward to speaking with you further. But for now I think I may partake in some refreshments and then head back to the Sanctum. Good evening to you both." Truce nods respectfully to her and Crowley before departing their company.
